PUMP-MOTOR.

SPECIFICATION forming part of Letters Patent No. 458,928, datedSeptember 1, 1891.

Application filed April 9, 1891. Serial No. 388,270. (No model.)

To all whom t may concern:

Be it known that I, GEORGE F. WIGHTMAN, a citizen of the United States,residing` at Traer, in the county of Tama and State of Iowa, haveinvented a new and useful Pump- Motor, of which the following is aspecification.

This invention relatesio motors for operating pumps; and the objects inview are to provide a motor of cheap and simple construction which maybe set and will automatically Operate a pump.

Other objects and advantages of thc invention will hereinafter appear inthe following description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings, Figure 1 isa side elevation of a motorconstructed in accordance with my invention. Fig. 2is a plan view of thesame on a large scale.

1 designates the opposite four uprights comprising a tower, whichuprights are suitably braced to form a stable structure and are cappedor snrmounted by a platform 2, from `whicl1 depend hangers 3, carrying aloose pulley 4r, over which passes a rope or cable 5, to one end ofwhich is connected a weight G for operating the motor now to bedescribed.

7 designates a pair of parallel sills located at one side of andprojecting under the tower, and from said sills rise opposite pairs ofvertical standards or posts S, each pair of which supports a pair ofside beams 9. Boxes 10 are mounted upon the side beams near one end, andin the same is journaled apower or drum shaft 11, at the ends of whichare located a large gear 12 and a smaller gear 13, and at one side ofthe large gear a ratchet 14:, which is engaged by a pawl 15, pivotedupon the gear 12, so that the latter gear will move with the shaft 11when the latter is driven in one direction.

In boxes 16, located near one end of the side beams 9, is journaledawinding-shaft17, having a crank 18 at one end, by which the shaft maybe operated, and asmall gear 19 at the opposite end, which engages withand drives the gear 13 and also the drum-shaft.

The shaft 11, as its name denotes, carries a drum 20, and around thesame is passed the rope or cable 5.

In boxes 2l in front of the drumvshaft is mounted an intermediate shaft22, carryinga small gear 23, rigidly mounted thereon and engaged andoperated by the large gear 12 of the drum-shaft when the latter isoperated by the rope or cable. The shaft 22 also carries a large gear2t, which engages and operates a small gear 25, located upon the shaft26, journaled in the side beams and carrying a large gear 27. The gear27 engages with and operates a small gear 2S, which is mounted upon ashaft 29, journaled in boxes 30 and carrying at one end a balance-wheel31 and at the other a pitman-wheel 32.

A brake-lever has one end pi\'oted,as at 34, to one of the side beams,and beyond its pivot is adapted to bear against the periphery of thebalance or ily wheel 3l, thus acting as a brake upon the mechanism andserving to arrest the motion of the same. This lever may be lockedeither in or out of position by a removable pin 35, passed through aperforation 3G, formed in the lever, and into any one of a series ofperforations 37, formed in the adjacent side beams 9.

Beyond the frame work and mechanism thus described, and at the other endof the sills 1, there is mounted upon said sills a post 38, to the upperend of which is secured a bracket 39, upon which is fnlcrumed, as at 40,a long lever or beam 41. The longer end of the lever extends to a pointvertically above the pitman or drive-wheel 32 of the motor, and isconnected to the latter by means of a pitman 42. Intermediate itsfulcrum-point and its longer end the lever is guided by a strap orkeeper 43, secured to the face of a postete, also mounted upon the sills1 intermediate the fulcrumpost 38 and the motor.

Between the posts 3S and 44 a series of teeth 45 is formed upon theupper edge of the lever 4.1, and a Weight I6 is mounted thereupon andmay be adj usted toward or away from the fulcrum-point of said lever. Acase or box 47 is located intermediate the posts 38 and at and upon thesills, and in the same is located an air pump or cylinder 4S, having afaucet 49 and a piston-rod 50, the upper end of which is pivoted, as at5l, to the lever 41. Beyond the sills is located the pump 52, ofordinary construction and having its pump-rod 53 pivoted, as at 54, tothe shorter end of the lever 41.

In operation the operator revolves the crank 18 and transmits motionfrom the windingshaft 17 to the drum-shaft 11 through the medium of thesmall and large gears 19 and 13, respectively. In this manner the ropeor cable is wound upon the drum and the weight elevated to the upper endof the tower. The brake-lever is now removed from Contact with theflywheel 31 and the operation of pumping begins, it being obvious thatas the pitman-Wheel is revolved an oscillatory motion is transmitted bythe pitman to the lever .41 and a reciprocatory motion transmitted fromsaid lever to the pump-rod 53 and the piston of the air-pump. The weight46 is adjusted to suit pumps of various drafts, and acts as acounterbalancing-weight, while the air-pump serves as acushion,preventing jarring, jerking, and decreasing friction. Bymanipulating. the key of the faucet 49 the motor may be regulated, aswill be obvious.

From the above description, taken in connection with the accompanyingdrawings, it 30 will be obvious that Ihave provided a weightoperatedmotor of cheap and simple construction, in which the weight may berapidly wound to an elevated position, and when so elevated will exertits influence upon the motor to operate the same, and the latter issogeared as to increase to a maximum the motion transmitted thereto;also will it be obvious that the air cylinder or pump will serve toregulate the speed of the pumping as well as act as a cushion andprevent jarring and jerking ofe the machinery at the end of each strokeof the pump, and, furthermore,

that the weight 4G counterloalanees the work-- ing of the pump, so thatthe motor may be operated by a small weight requiring but little energyor power to elevate it to an operative position.

Having described my invention, what I claim is 1. The combination, withthe fulcrum, the lever mounted pivotally thereon and adapted at one endfor engagement with a pump or other rod, and the motor for operating thelever, of an air-pump located between the motor and fulcrumprovided witha faucet, and having its piston-rod pivoted to the lever, and the Weightadjustably mounted on the lever between the fulcrum and motor,substantially as specified.

2. The combination, with the fulcrum, the lever mounted thereon andadapted at one end to engage with a pump or other rod, and the motor foroperating the lever, of an airpump located between the motor andfulcrum, provided with an air-faucet, and having its piston-rod pivotedto the lever, substantially as specified.

to one end of the cable, a pitniau-wheel, and a train ot' gearing foroperating the same, of a fulcrum-post, a lever fulcrumed upon the post,a post located between the motor and fulerum and having a keeper for thelever, a series of teeth located upon the lever, an adjustable weightmounted in the teeth, a pitman connecting one end of the lever with thepitinanwheel of the motor, an air-cylinder located between the two postsand having a regulating-faucet, and its piston-rod pivotally connectedwith the lever, substantially as specified. f

Intestimony that I claim the foregoing as my own I have hereto affixedmy signature in presence ot' two witnesses.
